1.创建项目时的初始化值
from django.conf.urls import url from django.contrib import admin urlpatterns = [ url(r'^admin/', admin.site.urls), ]
2.创建多个app时可以使用include()函数完成分流
from django.conf.urls import url from django.contrib import admin from django.conf.urls import include urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^app01/', include("app01.urls")), url(r'^app02/', include("app02.urls")), ]
3.引入视图函数完成url与函数的对应关系
from django.conf.urls import url,include from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^index/', views.index), ]
4.给url取一个别名
from django.conf.urls import url,include from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^index/', views.index, name='别名'), ]
5.正则匹配url和伪静态结合
from django.conf.urls import url,include from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^index/(\w+).html$', views.index), ]
6.重点介绍一下Django里面url别名
"""url别名是Django才有的特性，通用标准还是在后端生成url再传递给html""" from django.shortcuts import render, HttpResponse from django.urls import reverse def index(request): """ 可以通过reverse反向查询url，在数据库层面则根据不同用户权限存储url别名 :param request: :return: """ # 1.在这里可以直接查询数据库获取url别名，然后传入render() url_list = [ 'url_one','url_two','url_three' ] # 2.url = reverse("url_one") # 也可以通过别名直接反向获取url然后传入render() return render(request, 'index.html', {'url_list': url_list})
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> </head> <body> <h1>菜单</h1> {% for i in user_list %} <a href="">c1</a> {% endfor %} <ul> {% for i in url_list %} {# 这里传入url直接放在双花括号中 #} <li>{{ i.id }} | <a href="{{ i }}">编辑</a></li> {# 如果是别名则是花括号加百分号和url反向生成url #} <li>{{ i.id }} | <a href="{% url i %}">编辑</a></li> {% endfor %} </ul> </body> </html>
